The Patriot MK2 is a 340 g/m² Hybrid Fleece jacket designed as a mid-layer or outer layer in cold, dry conditions: hunters, shooters spending time at the range during colder seasons, and operators working outdoors with significant temperature swings. Compared to the previous single-layer heavyweight fleece version, this second generation brings the total weight down to 710 grams while improving breathability.
The Hybrid Fleece material combines two layers with distinct roles: the outer face is a classic fleece that retains body heat, while the inner face uses a cross-knit construction derived from Alpha jackets, distributing heat more evenly and wicking moisture away more quickly. The result is a workable balance between warmth and weight: the Patriot MK2 is neither waterproof nor windproof, so in rain it needs a dedicated outer shell, but as a mid-layer or outer layer in dry conditions it manages heat better than traditional fleece of the same thickness.
The cut is designed around freedom of movement: raglan sleeves eliminate the shoulder seam, reducing friction points against a vest or plate carrier worn over the top. The centre YKK dual-slider zip lets you open the jacket from the bottom when seated or in a vehicle without removing your harness. The collar features a chin and beard guard to prevent direct zip-to-skin contact. Underarm vents allow heat to escape during high-output activity without fully opening the jacket. The extended rear hem covers the lower back when leaning forward, while the adjustable drawcord hem stops cold air from pushing up inside.
Key features
- The 340 g/m² Hybrid Fleece fabric balances warmth and breathability better than single-layer fleece, keeping total weight under 710 grams.
- Raglan sleeves reduce friction against load-bearing systems worn over the jacket and allow full shoulder mobility.
- The bi-directional YKK zip with chin guard lets you open the jacket from the bottom without removing overlying equipment.
- Seven pockets in total — two large lower front pockets accessible with winter gloves, two flat chest pockets, two shoulder pockets with velcro for patches and pens, one internal — cover a range of organisational needs without adding unnecessary bulk.
- Underarm vents and the adjustable hem let you regulate heat on the move without taking the jacket off.
- Made entirely from 100% polyester: dries quickly and does not absorb odours the way natural materials do.
